Abstract (en)
[origin: EP2868653A1] In production of a cationic lipid having at least one methylene group sandwiched between adjacent two cis form double bonds in the molecule, isomerization from a cis form to a trans form is suppressed. A compound represented by the following formula (I): €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒR 1 -X€ƒ€ƒ€ƒ€ƒ€ƒ(I) (in Formula, R 1 represents a hydrocarbon group having at least one methylene group sandwiched between adjacent two cis form double bonds in the molecule and having the carbon number of 8 to 24 and X represents a releasing group) is reacted with (B) a compound having at least one of each of tertiary amino group and hydroxyl group in the molecule in a saturated hydrocarbon solvent having the carbon number of 5 to 10 in the presence of an alkali catalyst.
